Abstract The invention relates to a bookbinding process in which each page is glued by its dorsal edge, characterized by the fact that a coating consistent with the used binding glue is deposited, before folding and cutting of the signatures, along one or more areas located on both sides of the folding lines of the paper sheet for forming said signatures, that after folding and assembling several signatures the dorsal part thereof is trimmed in such a manner that the coated area emerges on the dorsal edge of the pages, and that the thus obtained assembly of pages is glued by means of an appropriate binding glue, as well as to the binding obtained by this process in which the faces of the pages comprise in a zone next to the dorsal edge thereof a layer of a coating which easily binds itself with the binding glue used.
A bookbinding process comprising applying adhesive along both sides of the folding lines of paper sheets, cutting, folding and assembling the sheets to form signatures, assembling a plurality of said signatures and trimming the dorsal part thereof so that the coated areas emerge on the dorsal edges of the pages, and gluing the thus-obtained assembly of signatures along said dorsal edges with bookbinding glue.

Dependent Claim
64 words
A bookbinding process comprising applying adhesive along both sides of the folding lines of paper sheets, cutting, folding and assembling the sheets to form signatures, assembling a plurality of said signatures and trimming the dorsal part thereof so that the coated areas emerge on the dorsal edges of the pages, and gluing the thus-obtained assembly of signatures along said dorsal edges with bookbinding glue.
Claim 3
Dependent Claim
24 words
A process as claimed in claim 1, in which each coating area is applied so as to overlap a folding line of the sheet.
Claim 4
Dependent Claim
22 words
A process as claimed in claim 1, in which each folding line of the sheet is bordered by two spaced coating areas.
Claim 5
Dependent Claim
14 words
A process as claimed in claim 1, in which the coating areas are rectilinear.
Claim 6
Dependent Claim
18 words
A process as claimed in claim 1, and gluing said pages to a support with said bookbinding glue.
Claim 7
Dependent Claim
14 words
A process as claimed in claim 1, and incorporating solid particles in said adhesive.
Claim 8
Dependent Claim
39 words
A binding made by the process of claim 1, comprising a plurality of pages whose dorsal edges are coated on opposite sides thereof with an adhesive, and a quantity of bookbinding glue securing said pages together in a book.
